cyma
A convex moulding on a cornice is called a TORUS if it is semi-circular or an OVOLO if its not. When combined with a concave moulding it is called a CYMA where the concave is at the top or a OGEE where the convex is at the top.
It depends whether it's a concave or convex lens. If it's a convex lens - the thickest part is at the centre. With a concave lens, the thickest part is around the edge.
Higher pressure on the convex side (from the heart contracting) than the concave side causes them to open. When the pressure reverses (the heart relaxes) they close.
The Necker cube is an optical illusion discovered in 1832 by crystallographer Louis Albert Necker. In a Necker cube, a two-dimensional drawing of a collection of cubes seems to open in different directions on the page.Graphic artist M.C. Escher incorporated Necker cubes in many of his works. Some examples of this are in his pieces entitled Convex and Concave, Belvedere and Metamorphosis.
Convex mirror form only one image(virtual) because it diverges light rays(beam).

concave
convex molding.
It can be convex or concave.
concave is inward, convex is outward concave is inward, convex is outward

The mold for a concave object is convex.The mold for a convex object is concave.
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
